Knowing how to use Twitter effectively to advance media and promotion goals has become a crucial skill. Naturally, there are a host of business and publications that seek to help you out, some charging up to $150 for the privilege. Now you can visit Twitter itself for its own best-practices blog. And it’s free. Called “Twitter Media,” the new blog has entries so far on choosing the right API (application programming interface), how to fight off Twitter cybersquatters and a look at tweeting from Haiti. Don’t worry, though, the entries are more informative and substantive than the 140 character-maximum of Twitter’s signature “Tweets.”
